The Lunar abundances roughly track Earth abundance. However, in many cases elements on Earth are concentrated by water chemistry, plate tectonics, the oxygen in the atmosphere, and weathering, over billions of years. In some cases, lunar element extraction will need mass spectrographic separation from undifferentiated rock, rather than ore location and refining. Bad news for some of the rarer materials.

Elemental Composition of Lunar Crust

(and Earth Crust)

various sources, not especially accurate

The Lunar abundances roughly track Earth abundance. However, in many cases elements on Earth are concentrated by water chemistry, plate tectonics, the oxygen in the atmosphere, and weathering, over billions of years. In some cases, lunar element extraction will need mass spectrographic separation from undifferentiated rock, rather than ore location and refining. Bad news for some of the rarer materials.

Beneficiated ore deposits are easy to find on the moon, you look for them under palm trees. :-(
